Research On The Creation Of Educational Resource Knowledge Graph Based On CiteSpace

With the rapid development of internet technology and the popularisation of wisdom education,some related basic theories of pedagogy and education techniques have an all-round development and innovation.Moreover,the increasingly diverse content of subjects,the more and more complex knowledge structure and the growing number of research scholars make the educational application and research resources increased day by day.As a perfect combination of education and technology,educational technology subject has a prospective guiding significance in education field.Meanwhile,the research papers on education technology is the latest reflection of its development.The number of papers is increasing and the connection between them is getting closer.Thus,the quantitative research on educational technology literature is helpful to grasp the subject structure and development sequence as a whole,and also promoting development and innovation of the educational technology.The main research contents of this paper are as follows:(1)The acquisition and preprocessing of target data.Firstly,4,038 original documents are collected by retrieving the CSSCI database.Secondly,2,452 available documents obtained after deduplication and format conversion.Thirdly,structuring different specific data sets in the network graph of keyword,author and reference by analysing the data characteristics of all the available data and different operation processes for different knowledge graphs.Last but not least,prove the necessity of structuring a specific data set.(2)The analysis of research hotspots of educational technology literature.This paper elaborates the construction process of keywords co-occurrence graph.First is to structure the co-word matrix via co-occurrence frequency of keywords.Next step is to construct keywords co-occurrence weighted matrix and graph streamline through pathfinder algorithm.Finally,hot topics of educational technology literature can be found on the basis of co-word clustered.In the end,prove the accuracy and availability of the experiment by compared verifying the experimental results.(3)The basic knowledge analysis of educational technology literature.By using the reference relations between papers,the authors and the references co-citation graph can be constructed.The author(reference)co-citation matrix can be constructed via co-citation frequency.Also,to construct the author(reference)co-citation weighted matrix and graph streamline through pathfinder algorithm.The core of the authors and high-quality basic papers in educational technology subject can be discovered combining with citied frequency and bet weeness centrality.Moreover,verify the experiment accuracy by secondary search.The ultimate purpose of this paper is to explore the construction principle and process of knowledge graph.Corresponding improvements are attempted to make on the basis of CiteSpace structuring knowledge graph through empirical analysis.On the other hand,that later researchers can grasp educational technology study contents,directions and hotspots quickly by combing existing researches,also influential authors and high-quality basic papers of educational technology can be discovered.This will provide strong basis and academic reference for future educational technology research and educational technology recourse exploitation.Thus,the development and application innovation of educational technology subject will be promoted.
